title: [CSF: diagnosis of neurosyphilis in a patient hospitalized for an acute brain stroke].
abstract: We report the case of a sixty-eight years old patient, who was admitted to the emergency for paresthesis associated with dysarthra and speech complaints. Neuroimaging revealed the presence of stenosis caused by arteritis. The notion of history of syphilis infection led to diagnosis of neurosyphilis. Diagnosis is difficult due to its clinical polymorphism and requires using several tests in the cerebrospinal fluid (CSF) because infection involving the central nervous system. Neurosyphilis is diagnosed by finding elevated cell count (80 leukocytes/mm3), high protein level (1.07 g/L) and positive IgG oligoclonal bands. In addition CSF and blood should be titrated with the VDRL and TPHA tests which are difficult to interpret. The diagnosis of active neuro-syphilis requires positive, non specific and specific inflammatory tests.
